Mononuclear Mn(II), Co(II), and Cu(II) pivalates

Polyhedron, 2014
Mononuclear Mn(II), Co(II), and Cu(II) pivalates were synthesized for the first time. They were isolated as salts with a composition NBu 4[MPiv3], where Piv is the pivalate anion. In the structure of the [MnPiv3] and [CoPiv3] coordination units, the environment of the central atom was found to be close to a trigonal prism.

Complexes of Cu(II), Co(II), and Ni(II) with "QPyNO"

Canadian Journal of Chemistry, 1971
A new ligand, 2,3-di(2-pyridine N-oxide) quinoxaline and its complexes with copper(II), cobalt(II), and nickel(II), have been prepared. A detailed investigation of the magnetic and spectral properties of these compounds has led to some tentative suggestions as to their structures.

Paramagnetic NMR investigations of Co(II) and Ni(II) amicyanin

JBIC Journal of Biological Inorganic Chemistry, 1999
The paramagnetic 1H NMR spectra of the Co(II) and Ni(II) substituted forms of the type 1 blue copper protein (cupredoxin) amicyanin have been assigned. This is the first such analysis of a cupredoxin, which has a distorted tetrahedral active site with the ligands provided by two histidines, a cysteine and a methionine.

Co(II)–Co(III) hydrotalcite-like compounds

International Journal of Inorganic Materials, 2001
Abstract The synthesis of monometallic hydrotalcite-like compounds (MHLC) type Co(II)–Co(III) materials was achieved by precipitation of a solution of cobalt nitrate(II) followed by microwave irradiation during the hydrothermal treatment step. The effects of irradiation time, precipitant agent and atmosphere were studied in order to establish the ...

Co(II) and Ni(II) Concentration, and Co(II) Purification with Microbiological Collectors (Saccharomyces cerevisiae)

Separation Science and Technology, 1978
Abstract Co(II) and Ni(II) can be concentrated quantitatively using a microbiological collector consisting of a Saccharomyces cerevisiae strain suspended in a glucose containing phosphate buffer. Optimal conditions for such accumulation as regards pH, time, and concentration have been studied. The influence of some complexing agents on the accumulation
